Paracrystallinity

WebFeb 1, 2013 · One factor in crystallinity is paracrystallinity (Hosemann 1962 ). It deals with deviations of the atoms from what would otherwise constitute a regular lattice. An extensive analysis of cellulose paracrystallinity was recently published by Ioelovich et al. ( 2010 ). WebIn materials science, paracrystalline materials are defined as having short- and medium-range ordering in their lattice (similar to the liquid crystal phases) but lacking crystal -like long-range ordering at least in one direction.
